FLANGE OILER Filed Oct. 14, 1929 2 Sheets-Sheet 2 Patented Jan. 23, 1934 FLANGE OILER Paul Irving Roberts, Caliente, Nev., assignor of one-half to Charles 0. Sportsman Application October 14, 1929. Serial No. 399,580 1 Claim. (Cl. 1843) My invention relates to flange oilers and has for its object to provide a new and efiicient oiling device for pumping the oil into the steam line which carries it to the front of the locomotive where the oil and steam mixture is sprayed on the flan es of front wheels of the locomotive.

further object is to provide a flange oiler which will be highly efficient in its operation, which will not clog and one which will carry 9; sufficient oil to supply the wheels of a locomotive longer period of time than has heretofore been accomplished.

A still further object is to provide a simply constructed flange oiler which will be positive in its action and which cannot clog or wear because all working parts operate within a closed casing.

A further object is to provide a flange oiler in which neither dust nor foreign particles of any type may accumulate and which oiler is so constructed that should foreign particles be in the oil, it would settle in the bottom thereof without being carried therefrom.

These objects I accomplish with the device illustrated in the accompanying drawings in which similar numerals and l tters of reference indicate like parts throughout the several views and as described in the specification forming a part of this application and pointed out in the appended claim.

In the drawings in which I have shown the best and most preferred manner of building my invention, Figure 1 is a vertical section on line 1-1 of Figure 6, dotted lines to indicate the travel of the operating rack. Figure 2 is an enlarged vertical section of one of the pump members of my device. Figure 3 is a side elevation of the modified form of ratchet used with my device. Figure 4 is a side elevation of Figure 3 with the ratchet cover plate removed. Figure 5 is a vertical section of the device on line 5-5 of Figure 6. Figure 6 is a section on line 66 of Figure 1. Figure '7 is a section on line 7-7 of Figure 5.

In the drawings I have shown the casing as A and the cover therefor as B. The bottom of the casing A is made of sufficient thickness and has a steam opening 1 therein; another opening 2 is formed at right angles to the opening 1 and the opening 2 is bifurcated to a cross bore 3 and pipes 4 are screwed into open connection with the bore 3 and pipes 5 are connected with the pipes 4 by suitable T couplings. To the bottom of the casing A, I provide a plate 6 which plate 6 is secured to the said casing by bolts '7.

Said plate 6 is perforated to receive a coupling 8 and an elbow 9 connects the bore of the coupling 8 with the pipes 5. On the top side of the plate 6 and passing up through a hole in the bottomof the' casing A, I provide two spaced apart upright castings 10 which castings have bosses 11 formed on the top end thereof at right angles thereto, and the lower portion 12 of the casting 10, has a mill cut 14 partially therethrough, which mill cut is the oil outlet from within the casing. I then provide a bore 16 through the boss 11 and a smaller bore 16 through the lower portions 12, and a bo1'e'39 is extended down through the base of the casting 10, where it is enlarged to a larger bore 41 which to bore 41 has a valve seat 40 formed at the periphcry of the bore 39 and the top end of the bore 41. A plunger 13 is passed down through the bore 16 of the boss 11 and the lower end of the plunger is made of smaller diameter to fit the bore 16 and operate up and down within said bore. A spring 13a is placed around the plunger 13, and a cotter pin 13c holds a washer 13b spaced from the bottom end of the larger portion of the plunger, thereby holding the spring so tension against the washer and the bottom of the boss 11, normally holding the plunger down with the shoulder of the larger portion of the plunger, resting on the top side of the portion 12 and with the end of the smaller portion of the plunger below the level of the cut 14. The said plunger 13 is provided with a large head 17 on the top end thereof to operate the plunger thereby. A ball valve 12 is carried within the bore il and is normally held to the seat 40 by 96 the spring 43 which spring is held in the bore 41 by a perforated screw plug 44. This construction provides communication between the cut 14, the bore 39, the bore 41, into the coupling 8, the elbow 9 and the pipes i and 5. 9-5

To operate the plungers up and down I provide a horizontal drive shaft 23 across the casing A and carried in suitable bearings 24 on each side of the casing. On the said shaft I then secure two spaced apart rings 18 and 22 and the rings are provided with actuating dogs or lugs 19 and 20. The dogs 19 and 20 are adapted to rotate with the shaft and come into contact with the heads 17 and raise the heads as they continue to rotate, until such time as they have raised the head to the maximum position, when the dog passes from under the head by its rotation, and the plunger and head is again driven back to its normal position by the springs 13a. As the plunger is raised the oil in the casing willllO flow through the cut 14, into the bore 39 and as the plunger is again forced down by the spring the oil in the bore 39 will be forced by the ball 42 and out through the coupling 8, the elbow 9, into the pipe 5, where the steam from the pipe 4 will be mixed with the oil and will carry the oil to the flanges of the wheels.

To actuate and rotate the shaft 23, I secure a toothed ratchet wheel 25 thereon adjacent one side of the casing A and a ratchet toothed rack 32 is carried over the top side of the said wheel to rotate said wheel when the rack is moved in one direction thereover and to slide over the teeth of the wheel when the rack is moved in the opposite direction. To insure that the dogs of the rack engage with the teeth of the wheel, I provide a small spring 33 to press down on the top side of the rack at all times although it is obvious that the weight of the rack would normally engage the teeth. The said rack is operated by a shaft 29 which shaft is attached on one end to the rack by the coupling 31 and the other end of the said shaft is attached to any suitable source of power by the coupling 30. The source of power may be from the link driving the valves of the engine or from any other suitable source of motion. The said shaft 29' is passed through one side of the casing A at a position 27 which portion of the casing may be made thicker than the balance of the casing, and a packing may be placed around the shaft 29 and held in place by a packing nut 28which nut 28 may be made of sufficient length to act also as a guide for the said shaft.

On one side of the casing A and spaced below the ratchet wheel 25, I provide two bosses 34 and 36, with the boss 34 adapted to hold a dog 35 pivoted therein, said dog 35 to engage with the teeth of the Wheel 25 to prevent the wheel from rotating in the wrong direction when the rack 32 is being drawn backward there- 7 over, and the boss 36 is to hold a spring 37, which spring normally holds the dog 35 engaged with the teeth of the wheel 25 but allows the dog to slide over the teeth of the wheel when it is being rotated by the rack 32.

In the modified form of driving power for the shaft 25 shown in Figures 3 and 4, I have pro vided a cover plate 45 in which the end of the shaft is carried and the shaft is extended out through the side wall of the casing A where a ratchet wheel 46 is secured thereon. An operating dog 4'7 is provided on a lever arm 48, said arm 48 to beactuated by a shaft 49 from any suitable source and the dog 47 to rotate the ratchet wheel when the arm 48 is moved in the opposite direction. A stop dog 50 holds the ratchet wheel 46 from rotating when the arm is moving backward.

Having thus described my invention I desire to secure by Letters Patent and claim:

In a device of the class described the combination of a covered oil casing, two spaced apart plunger pumps mounted through the bottom of said'casing; pipes connecting said pumps with steam carrying pipes to carry the oil mixed with steamto the wheel flanges; a horizontal shaft mounted across said casing; lugs secured to said shaft adapted to operate the plungers of said pumps when said shaft is rotated; a ratchet Wheel carried on said shaft; a spring held dog to prevent rotation of said wheel in one direction; and a toothed rack to be operated over said ratchet wheel to rotate said wheel when the rack is moved in one direction and to slide over the teeth of the wheel when moved in the opposite direction.
